I really need some suggestions. I am a Mopar guy, but my buddy has a 69 big block Chevelle and I am stumped. It has a Q-jet with automatic. When rolling about 40 mph in 3rd and you barely increase the throttle it starts stumbling and even loses all power until you back off the throttle a bit...

Could you please posts some pictures of your bypass regulator at the carb. I am going from a deadhead to a bypass in the next couple of weeks and am going to be gathering the fittings and like and would like some ideas. Here is a picture of my current system. Also, the reason for the change...

After not starting for a couple or a few months, it was a sumb**tch, to get the Dart going...crank, crank, sputter, backfire, then when it does catch, afterfire in the exhaust. Pull the plugs and they are black and wet with fuel. I finally have started draining the front bowl of the carb and...

Hi All, Have always been happy with my Holley 750 HP, except when starting cold. There is no choke and would take about 4 to 5 times of starting to keep running, then good. I purchased a new Quickfuel 850 with mechanical secondaries and electric choke. Throttle response is markedly...

I started the Dart yesterday, but it took a lonnnnggggg time to start. Wondering if the older 93 octane gas contributed to the difficulty. Here's the details.... Sitting in garage with temps going from 30 degrees to 60 degrees for the past 5 months Holley HP 750 (no choke) (I may switch...

I have an Edelbrock 1792 electric pump. The Dart has about 1500 miles on it. I had set the pressure on the regulator to 6.5 psi. Yesterday on the way home, it kept going down.......down to 3.5 psi by the time I got home. Pump did not sound the same, like it was not under a load. Sound like...

....and close to 80 mph!! Took the Dart out on a country road about 5 miles from the house. Got on it in 2nd, spun too much, probably close to rev. limiter, peddled a little and got traction, up to about 6K, shift to 3rd. Immediately fuel started spraying all over the windshield from out of...

I have a 71 Dart with the factory gage. Currently running a 12 gallon Jaz cell with their 70-10 ohm sender, 70 empty and 10 full. If I fill the cell to within 1" of the top, the gage will indicate about 3/4 full. After using only about 4 gallons the gage is on E. It sounds like I have too...

I have been tuning a little at time in the past few months. I had left the Power Valve alone, but realized I was pretty far off. Original PV in the Holley 750 HP was 6.5, but after checking the vacuum at idle in gear it was hovering around 5 inches (does this seem too low??). I went to a 3.5...

At times I have a bit of a time starting. When cold no problem, couple of good full throttles and alive (temp about 60). I came in after running pretty hard yesterday and it sat about an hour (outside temp about 60). I gave it about a primary full of pump and it cranked and cranked. I gave a...

Please help me choose a new different carb. Problem is that I have a Holley 750 HP, which has no choke and it takes about 3 starts to get it warmed enough to keep it running good. After about 2 minutes its fine and I am very happy with it. I would like to stay with the performance, mainly street...

I have a 71 Dart with a 4 3/4" cowl hood. I am going to be mounting my fuel pressure gage and would like to get some ideas of what everyone else is doing. I really don't want to start drilling holes in the cowl vent area. Appreciate your feedback.........Thanks.

Just thought I would through this out if anyone is looking for a cool simple way to eliminate the fuel cap when running a cell in the trunk and not have the filler in the original position. The simple drawing is below the picture and you should be able to print it by right clicking on the...
